I love flip flops too but I should buy some new, nicer ones since my flip flops from last year look worn out. I hate wearing them on rainy days... one word: OUCH.

For summer, I'm thinking wedge heels! Maybe it's just 'cause I'm short. They're much more comfortable than normal heels because the weight's distributed better. I remember that espadrilles were quite popular last year - maybe they will be this year as well? Either way, I invested in a pair of peep toe wedge heels, and a pair of sandal espadrilles.
